BE CAREFUL WHAT YOU SAY FROM NOW ON.
I bet there are at least 25 ladies who already know exactly which school you are talking about just from this first post.
If you talk about your outfits, stay vague (ie colorful Sundress as opposed to Lilly Pulitzer Tenley Shift).
If you talk about events, stay vague (ie something funny/embarrassing happened at Blue - NOT OMG! This girl at Blue totally dropped the punch bowl and it spilled all over this PNM's Jimmy Choos.)
You get the idea. You can give us a brief outline as you rush, and then come back and fill in the details after bid day.
